HR3

HR3 is a statistical method used to evaluate how well a predictive model performs, especially in the context of risk prediction. It focuses on the expected improvement in identifying true positive cases compared to a baseline model. Essentially, HR3 measures the added value a particular model provides in correctly classifying individuals at risk, helping researchers and practitioners determine if a new model offers meaningful enhancement over existing approaches. It’s a useful tool for assessing the effectiveness of risk scores or predictive algorithms in fields like healthcare and finance.
